SPECIFICATION forming part of Letters Patent No. 396,830, dated January29, 1889. Application filed July 21, 1887. $erial1lo. 244,872- (Nomodel.)

To aZZ whom it may concern:

. Be it known that; I, A. GORDON M URRAY, a citizen of the UnitedStates, residing at Cedar Rapids, in the county of Linn and State ofIowa, have invented certain new and useful Improvements inSash-Fasteners, of which the following is a specification.

The object of my invention is to produce an automatic fastener forwindow-sash and the like which shall be capable of holding the sash atany desired point and shall be easily 1 operated to fasten or unfastenthe sash.

The invention consists in the application, as hereinafter set forth, ofmovable slide or block having a diagonal face, a holder adapted to holdthe sash by wedging between the face of the slide and the j amb orcasing, an d means for engaging and-disengaging the operative parts.

In the accompanying drawings, fm'niing a part of this specification,Figure 1. represents a front elevation of the invention applied toportions of sash and window-jamb; Fig. 2, a rear elevation of. theinvention; l ig. 3, a similar view of a modification thereof, and Fig.et an elevation showing the outer edge of the fastener and a portion ofsash.

Similar letters of reference indicate corresponding parts.

As shown in the principal figures, the device IS designed. to beattached to the face of the sash, and, while suitable for any window, ismore specially applicable to car-wimlows.

The modified form of device shown in Fig. 5 is more particularlydesigned for ordinary windows, and its C(HlSti'llCtiOll issucli as tohold the window either up or down.

In the drawings, A rep resents the sash, B the jamb, and C the stop,inFigs. 1, 2, and l. The case D of the fastener has a diagonal rib, a, Insuitable lugs, I) Z), is fixed a guide-pin, e, which may be a screw, asindicated. This slide has a rib, (7, corresponding to that of the ease,and the lower portion of this rib forms a pocket for the reception ofthe holder 11. A lug, c, of the slide is adapted to slip on the pin 0.The lower end of the slide is preferably held in position by the screwf, which, in connection with a similar screw, f", secures the fastenerto the sash. This screw passes through a slot, g, in the slide andadmits of the diagonal motion of the slide,as indicated by the dot tedlines in Fig. 2. The same object is effected by the construction shownin Fig. 3; but that 5 5 shown in Fi 2 is preferred, as it admits of theguide-pin being made shorter, and brings the screw f into a morerelatively central position with respect to the case l).

The slide E is forced in the upward direction by a spring, 72, mountedon the guide-pin c. The movement in the contrary direction is effectedby a finger-lever, G, the pivot 2' of which may form a part of the caseD or be one of the screws by which it is fastened to the sash. Abovethis lever and forming a part of the case is a thumb-piece, j.

In the open space outside the diagonal face of the slide is placed theholder F. This is preferably a round disk, as shown in all but Fig. 3 ofthe drawings, and in practice I make it of quite hard rubber, thuscausing it to adhere the more readily to the window-stop O, and thiswithout bruising or otherwise injuring it. A hard disk, of metal or thelike, rimmed 7 5 with rubber or equivalent material would answer thesame purpose. This part holds the sash at any desired elevation bysimple pressure, due to its wedging action, as it rolls up the inclineof the slide E. It is not indis- 8o pensable that this holder should beround or that its face should be elastic, though I regard both thesefeatures as desirable and important for the reasons already stated. InFig. another form is shown, the holder F being triangular and adapted toslide up the face of the slide E. Corrugations k on the vertical face ofthe holder serve, like the rubber face of the disk in the other case, toincrease the friction of the holder on the window stop or jamb. The faceof the hard disk might in the same way be notched or corrugated; but asthis tends to mar the woodwork a yielding material is preferred. It willbe observed that by this construction the slide serves in a threefoldcapacity-as an inclined bearing for the roller .or wedge and asapositive means for engaging and disengaging the same with and from thejamb. \Vhether diagonal or horizontal, the motion of the slide .istoward or away from the jamb, and the l key, beingheld in a pocket orseat in the slide, is pushed positively toward the jamb for engagement,while the opposite motion tends as positively to disengage the partswithout any movement of the sash. The latter effect is evidently greaterwith the roller than with the Wedge; but the principle is the same ineach case, the contact of the inclined surface of the slide with thewedge or roller tending to loosen the fastening by the outward movementof the slide.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In. a sash-fastener, the combination of the ease D, thediagonally-moving slide E, having a diagonal 'laee opposite the window 1stop or jamb, the holder F, and the fingerlever G, all eon strueted,arranged, and adapted to operate substantially as and for the purposespecified.

2. In a sash-faster1e13the combination of the ease D, the inclined pin0, the diagonallymoving slide E, having lug 9, adapted to slip on saidpin, and slotg, adapted to allow the slide to move on thefastening-screw f, the holder F, and the finger-lever G, substantiallyas and for the purpose specified.

In testimony whereof I affix. my signature in presence of two witnesses.

A. GORDON MURRAY.
